Ray Tracing using Hierarchies of Slab Cut Balls

al / A Spatial Representation for Ray-Scene Intersection Test Improvement in Complex Scenes a photon tracing system.. The resulting rays are used

The first variant RT static consists of a static ray tracing pipeline using a ray-triangle intersection algorithm I w based on Wald [Wal04] and simple shading unit S that only

We introduce a new ray tracing algorithm that exploits the best of previous methods: Similar to bounding volume hierarchies the memory of the acceleration data structure is linear

We have tested our algorithm on the Patio scene, chang- ing its complexity from 21K to 705K triangles, and using three di ff erent specular reflectors: a smooth sphere, a 69K

Most current methods involve minimizing a cost function based on the L 2 -norm between a rendered face model with a particular set of parameters and a target image.. As the

While the core ray tracing algorithm might be embarrassingly parallel, scaling a ray tracer to render millions of pixels at real-time frame rates on a cluster remains challenging;

Let T cost (A) denote the computational cost to test if a given ray hits node A, ie: number of instructions needed to test ray hits against A bounding volume.. Using the
